ASC workers take strike action in Adelaide

Shipbuilder ASC has pledged to continue negotiations on a new enterprise agreement as workers engage in five days of industrial action after what they say has been two years of little progress.

The Australian Manufacturing Workers' Union says ASC workers are unhappy about proposed revisions to their enterprise agreement that would strip back rights and entitlements.

AMWU acting state secretary Colin Fenney says workers are taking a rostered day off on Friday and will not work on Saturday or Sunday because of a ban on overtime.

They will also stay on strike on Monday and Tuesday.

"Workers have been left with no option but to engage in protected industrial action," Mr Fenney said.

"This is the first time that ASC has sought to impose Australian Public Service guidelines on its workforce which is removing flexibility from the ASC enterprise agreement and clearing the decks for privatisation."

In a brief statement on Friday, ASC said it would continue to seek a resolution to the current dispute.
